Asked a few people on this forum, and they're experiencing the same thing. I found that the speakers are positioned strangely: the "left" speaker is centered, while the right speaker is placed where the CD drive is. Coupled with the fact that the right speaker is also where the subwoofer is, it creates the feeling that the sound projects mostly from the right side of the laptop.

It's not noticeable for certain songs that are less bass-heavy. For example, try listening to John Legend - Ordinary People. It will sound relatively centered. Quite strange indeed.

Regardless, I doubt I'm going to return the laptop. I think this can be fixed with some sort of software update in the future.
